Note on Rhopalomyia pomum/calvipomum

If you iNat a Rhopalomyia pomum/calvipomum ("sponge gall midge" and "sagebrush plum gall midge" respectively), please include the surface texture in the notes: hard for calvipomum, soft/spongy for pomum. Ron Russo says this is a good way to distinguish these two that seem to overlap in morphology. Both are found on Big sagebrush (Artemisia tridentata). I have also seen this plant referred to as "Great basin sagebrush", which I think is a much better name.
